Integer type of files can be mapped for the Allen-Bradley PLC when being used with
the OP-1212. In the examples below, integer file registers starting at base address
N7:0
have been mapped. If you need more information on any of the features of the

Rung 1 -- Pushbuttons and Lamps
When pushbutton 7 is activated Lamps 3 and 4 turn ON.
Also, the LED in pushbutton 7 will turn ON if LED Separation
is disabled and the pushbutton is configured as maintained.
Rung 2 -- LEDs
When contact I:0/3 is ON, LED 9 turns ON
NOTE: Panel must be in LED Separation mode and pushbutton
configured as momentary.
Rungs 3 and 4 --Flashing Lamps
To flash a Lamp, it must be first turned ON When contact I:0/1 is
activated Lamp 5 will turn ON and when contact I:0/2 is
activated the Lamp will flash.
Rungs 5 and 6 -- Flashing LEDs
To flash a LED, it must be first turned ON When contact I:0/1 is
activated LED 1 will turn ON and when contact I:0/2 is activated the
LED will flash.
NOTE: Panel must be in LED Separation mode and pushbutton
configured as momentary.
Rungs 7 and 8 -- Force Function
When pushbutton 12 is pressed, process O:3/2 is started.When the
process is completed it activates contact I:0/5 which forces
pushbutton 12 OFF.
NOTE: The pushbuttons must be configured as maintained (alternate)
and the panels ”Force Function” feature must be enabled.
